采用90 nm SiGe BiCMOS工艺设计并制作了一种适用于100-GBD光发射机的线性驱动器。提出了一种输出摆幅限制电路和多拓扑峰化方法来扩展带宽。该驱动器在67 GHz以上的带宽下获得了21分贝的差分增益，每侧输出1分贝压缩点(Po1分贝)超过11 dBm，对应的差分输出摆幅超过4.5$V{mathm{ppd}}$。该驱动器与硅光子学Mach-Zehnder调制器共封装在相干光学组件(COSA)模块中。该模块成功地实现了96-GBD双偏振16QAM光产生和检测。
A linear driver for 100-GBd optical transmitters was designed and fabricated in the 90-nm SiGe BiCMOS process. An output-swing-limiting circuit and multitopology peaking method are proposed to extend the bandwidth. The fabricated driver achieved a differential gain of 21 dB with a bandwidth of over 67 GHz and a per-side output 1-dB compression point (Po1dB) of over 11 dBm, corresponding to a differential output swing of over 4.5 $V _{mathrm {ppd}}$ . The driver was co-packaged with a silicon photonics Mach–Zehnder modulator in a coherent optical subassembly (COSA) module. The module successfully performed a 96-GBd dual-polarization 16QAM optical generation and detection.
